  • Patent number: 11398705
    Abstract: A charging surface comprising multiple conductive regions can be used to charge an electronic device placed on it the surface so that electrodes on the device engage respective conductive regions of the surface. In order to distinguish such chargeable devices from short circuits and other spurious connections, the devices are required to demonstrate an anti-inversion characteristic, for example implemented with a MOSFET, across at least a pair of these electrodes. The surface can then be controlled so as to establish a text voltage across each pair of conductive regions in sequence, and look for pairs of conductive regions behaving as being coupled by such an anti inverter circuit. Relationships between every pair of conductive regions can be determined and recording, and the voltage level supplied to each conductive region set accordingly.

    Abstract: A charging surface comprising multiple conductive regions can be used to charge an electronic device placed on it the surface so that electrodes on the device engage respective conductive regions of the surface. In order to distinguish such chargeable devices from short circuits and other spurious connections, the coupling interface associated with the charging surface is controlled so as to establish a text voltage across each pair of conductive regions in sequence, and look for pairs of conductive region demonstrating a voltage drop characteristic of a particular class of device. Relationships between every pair of conductive regions can be determined and recording, and the voltage level supplied to each conductive region set accordingly. The coupling interface may furthermore operate to identify device classes, and to set supply voltages or establish additional connections on the basis of stored device class information.

  • Publication number: 20200127477
    Abstract: The invention discloses an adaptor or coupling arrangement for a device to bus contact connection. According to the invention, the coupling arrangement may be integrated in the device or configured to mate externally to the device. The coupling arrangement comprises electrical contact areas configured to mate to a mating surface that is itself configured to connect to a power line, one or more data lines, or both. The coupling arrangement also comprises an electronic circuit that is configured to perform one or more anti-inversion of current functions. Thus the coupling arrangement of the invention allows detection of the current connections established or not with conductive areas of the mating surface. Also, the coupling arrangement operates as a protection circuit that prevents any short circuit, whatever the positioning of the device on the mating surface. The coupling arrangement may be used to operate smart phones, tablets, laptops or other types of electrical appliances.

  • Patent number: 10511610
    Abstract: The invention discloses trusted computing nodes (TCNs) configured to control their location and migration of applications run on virtual machines resident thereon. The invention allows a controlled use of cloud computing resources and virtual network functions by sensitive applications. This is achieved by embedding a secure processing unit (SPU) and a localization unit (LU) in the TCNs. The LU acquires GNSS signals and the TCN generates a secure location message comprising a secure ID and a locstamp of the TCN. A TCN Registry may be created by an operator of a collection of TCNs as a database of trust scores of the trusted computing nodes which will be used to control the allocation of tasks to said TCNs based, at least in part; on the trust scores. The trust scores may also be used directly by the other TCNs to allocate the tasks which they have control on.

  • Publication number: 20150326887
    Abstract: The present invention concerns a method for dynamically adapting the lossy encoding of an audio and/or video stream (112) transmitted by a first device (101) to a remote device (102), said method comprising the following steps: the remote device (102) receives and decodes said stream (112), called the incoming stream, and transmits an outgoing stream (111) having at least one indicator relating to a state of said remote device (102) that is modified by the execution of the decoding of the incoming stream (112); the first device (101) receives the outgoing stream (111), extracts said at least one indicator therefrom and adapts the encoding of the incoming stream (112) according to said at least one extracted indicator. The method can be applied notably to video conferences conducted on the basis of self-powered terminals for the purpose of maintaining the operating period of these terminals.
